Endogas Generator


Gas carburizing processes and other heat treatments under protective gas, where the carbon exchange with the work piece surface plays a role, make high demands on the controllability of the atmosphere. The carrier gas procedure using endogas, proven since many years, offers the best conditions according process engineering for:

  • Exact process control
  • Best reproducibility of the final results
  •  High quality requirements.

The λ-probe control

The measuring gas is conducted through a temperature-constant -probe. At the same time a mV-signal is emitted by the λ-probe, which is used for measuring, control and regeneration of the endogas-composition and is displayed in mV. (optionally in °C dew point.) 

A very precise control of gas/air mixtures is required to produce constant quality of endothermic gas.

Quantity control

The endogas generator capacity can be adjusted to the required capacity manually or by automatic quantity control. The unused protective gas is burned off in manually controlled Endo Gas Generator. In automatic controlled quality control system the amount of Endogas is generated automatically with minimum wastage at burn-off.

Through adapted design and using the modern L-probe, a quantity control of the protective gas in the range of 100 %up to 50 % of the nominal capacity is now possible


  • Protective gas quantity according to requirements
  • Reduction of costs
  • No difficult manual adjustments

Fully automatic regeneration device (optional)

This device enables a fully automatic regeneration of the protective gas generator, whereby the start can be carried out

  • Manually
  • Automatically with time control
The production of protective gas is stopped automatically when the generator temperature is reduced to regeneration temperature, and the generator is regenerated afterwards. 
When the auto generation (de-sooting) mode is selected, the production of protective gas is stopped automatically. The generator temperature is reduced to the regeneration temperature and regeneration (de-sooting) is completed.
After the regeneration, the ENDOMAT® is automatically heated up again to operation temperature and prepare for protective gas production again.
